I think it's a lot easier to control with a vertical foregrip, though I've only fire a couple of ARs. But it's definitely good for minimizing muzzle climb on a happy switched m4gery!
I can't think of a downside. Mine can be unscrewed and taken off in about 5 seconds. It helps a lot shooting offhand.
VFGs are great when you need to turn the weapon quickly, like when clearing your home. They can be a problem when you're in the prone. It's going to boil down to a personal choice. Some folks love 'em, so hate 'em, and most probably fall somewhere in between.
I would have to say I hate them, they get in the way, and really don't add much to handling as far as my opinion goes. They are more of a tacticool addon than anything else. the only time I would have one is on a shorty, for obvious reasons.
i think they are useful, sometimes, but the prices for some of those things is just ridiculous. its a molded piece of friggin plastic and some prices are INSANE
I have one on my RRA entry tactical. It takes getting used to. I think I prefer it without the verticle handle. but I've shot rifles for 30 yrs without one.
It's definitely not going to be the first upgrade on my rifle. I'll probably go for upgraded HGs or optics first now that I've got a few magazines and some ammo covered now.
my AMD 65 doesn't have a choice The AMD 65 comes with one fastened to the rather slim metal handgaurd. It works pretty good but inserting 30 round mags or a drum can take a little manuvering around the grip to get em seated. [/img]
